The problem with the stuff on this list is:

1. Most of the patents have expired.

2. Most of the ones that haven't expired, expire soon.

3. The unexpired patents only cover specific configurations of VTOL craft, drone stabilization systems, and design improvements to rotary engines. There are lots of other configurations out there, drone manufacturers seem to be able to do fine with what is already out there, and no one else seems especially interested in rotary engines. So there isn't much here that is of value to anyone else.
